Below the order in the present invention and successively incremeantal launching method are explained, order in " order and successively incremeantal launching method " refers to first pushing tow the first transmission crank arm 51 of the first driving cam 49 and drives connecting lever axle to rotate, second driving cam pushing tow the second transmission crank arm 64 drives connecting lever axle to rotate subsequently, " order and successively incremeantal launching method " refer to that the second driving cam starts pushing tow this action of the second transmission crank arm and the first driving cam terminates not free interval between pushing tow the first transmission crank arm continuously, when cam axle, power continual can pass to connecting lever axle so that connecting lever axle rotates continuously.When needs switching-in spring energy storage, the power of motor passes to camshaft through transition axis thus drives camshaft to rotate counterclockwise (visual angle in Fig. 1), under the effect of unilateral bearing, first driving cam starts to promote the first transmission crank arm to rotate clockwise, and owing to the second driving cam also rotates counterclockwise, so the second transmission crank arm rotates counterclockwise reset under the effect of back-moving spring, owing to the reseting procedure of effect second transmission crank arm of unilateral bearing does not interferes with rotating clockwise of connecting lever axle, first transmission crank arm drives connecting lever axle to rotate clockwise, connecting lever axle is rotated clockwise by sprocket wheel chain-driving energy storage axle, energy storage pallet and the first chain joint are by switching-in spring chain-driving switching-in spring energy storage；nullWhen the first driving cam promotes the first transmission crank arm to peak，Second transmission crank arm is reset to minimum point，First transmission crank arm starts to rotate counterclockwise reset subsequently，Second driving cam starts to promote the second transmission crank arm to rotate clockwise，Under the drive of the second transmission crank arm，Connecting lever axle continual drive energy storage axle rotates clockwise，Switching-in spring continues energy storage，In switching-in spring thermal energy storage process，Switching-in spring can give one active force rotated counterclockwise of connecting lever axle，But owing to transmission crank arm is transmitted cam limit，The active force of switching-in spring will not pass to motor through drive mechanism，Ensure that the stability of thermal energy storage process，After switching-in spring energy storage terminates，Now energy storage pallet rotated respective nodes，By combined floodgate trip gear spacing with energy storage pallet coordinate thus limit energy storage axle rotate，So that switching-in spring is held in energy storage state，When needs breaker closing，It is spacing that the de-mouth device that closes a floodgate releases energy storage pallet，Switching-in spring drives connecting lever axle to rotate counterclockwise，And due to the effect of unilateral bearing，First、Second transmission crank arm is not rotated counterclockwise by connecting lever axle to be affected，Continue to be held in origin-location.After switching-in spring energy storage terminates, now energy storage pallet rotated respective nodes, switching-in spring can give one active force rotated clockwise of energy storage axle, first chain joint contacts with force block, and force block is had downward pressure, when the first back-moving spring is compressed to maximum, force block drives the cross bar of lever and montant to rotate counterclockwise, montant drives rotor plate to rotate counterclockwise by connecting rod, transmission crank arm jack-up is made transmission crank arm depart from corresponding driving cam by rotor plate, combined floodgate trip gear can be spacing to energy storage axle subsequently, even if now motor continues to run with, owing to driving cam departs from transmission crank arm, motor can only drive driving cam to dally, motor will not burn because of stall.
nullThe work process of this breaker operation mechanism is: motor drives energy storage axle to rotate by drive mechanism，Detent unit compresses switching-in spring energy storage by switching-in spring chain，When switching-in spring energy storage puts in place，Coordinate spacing with the energy storage pallet on energy storage axle sprocket wheel of combined floodgate trip gear prevents energy storage axle to be rotated further，Switching-in spring is held in energy storage state，When needs move、When static contact closes a floodgate，Combined floodgate trip gear releases spacing to energy storage pallet，Under switching-in spring effect，Energy storage axle sprocket wheel drives energy storage axle to rotate，Energy storage axis cam 58 coordinates with separating brake energy storage roller 32 pushing tow on integrated connecting lever in the process，Integrated connecting lever drives output shaft rotation，Output toggle arm drives moving contact towards the motion of corresponding static contact direction to realize closing a floodgate by output pull bar，Meanwhile tripping spring is by compressed energy-storage，Definition first、The arranged direction of the second radial direction right hole is first and last direction，So two ends of hinge hole are respectively head end and end，The most integrated connecting lever drives bearing pin to move towards the end of hinge hole，Owing to hinge hole is the elongated hole that a length extends along the longitudinal direction，Therefore at the beginning of closing a floodgate，Piston rod does not move，Buffer does not produces damping action to integrated connecting lever，Ensure that the combined floodgate initial velocity of moving contact，The end of hinge hole is moved to rear pin shaft，Piston rod starts to drive piston to move，Hydraulic oil enters between piston cap and piston through helping sorting hole，Ensure that piston cap is smoothly detached with piston，Axial oilhole on piston is not blocked by piston cap，On piston, the hydraulic oil in the side at the second radial direction oil hole place flows to pistons front sides through two lines road，Article one, circuit is the axial oilhole on piston，Another circuit is the second radial direction oil hole、Annular gap and the first radial direction oil hole，Two lines road ensure that the circulation area of hydraulic oil，Reduce the damping of hydraulic oil，And then reduce the buffer damping to integrated connecting lever，Reduce the buffer impact on switch on of moving contact process，And owing to the aperture of the second radial direction oil hole is more than the aperture of the first radial direction oil hole，So can further improve the through-current capability of hydraulic oil，Further reduce the damping of hydraulic oil，At the end of closing a floodgate，Sub-gate release device is spacing with separating brake roller to be coordinated，So that tripping spring is held in energy storage state.nullWhen needs move、During static contact separating brake，Sub-gate release device releases spacing to separating brake roller，Tripping spring drives integrated connecting lever to rotate，Output toggle arm drives moving contact towards away from the motion of corresponding static contact direction also by output pull bar，Integrated connecting lever drives bearing pin to move towards hinge hole head end，Owing to hinge hole is an elongated hole，Therefore at the beginning of separating brake，Piston rod moves the most forward，Buffer does not produces damping action to integrated connecting lever，Ensure that the separating brake initial velocity of moving contact，The head end of hinge hole is moved to rear pin shaft，Piston rod drives piston to move，The corresponding end of one end and piston cap of being closed on piston cap by hydraulic oil effect piston is close to，Axial oilhole on piston is blocked by piston cap，On piston, the hydraulic oil of side in the first radial direction oil hole place can only pass through the first radial direction oil hole、Annular gap and this circuit of the second radial direction oil hole flow on rear side of piston，The circulation area of hydraulic oil is little，The damping force of hydraulic oil is big，Ensure that the buffer damping to integrated connecting lever，And owing to the aperture of the first radial direction oil hole is less than the aperture of the second radial direction oil hole，Further add the damping force of hydraulic oil，Thus dampings different when realizing breaking-closing operating.Piston is made up of inside and
